What an ADU costs in Hollywood

Use $280-$420 per sq ft as the local planning range for a first pass. That puts a 600-1,000 sq ft ADU around $168,000-$420,000, while many California projects still fall in the broader $150,000-$450,000 range. The current CityStat permit valuation signal is $83,353, which is useful for comparing permit records but should not be treated as a full turnkey construction bid.

Permitting and timeline

Hollywood ADU permits are handled through LADBS under California's 60-day ministerial review rules for compliant ADUs. Confirm lot-specific setbacks, height, parking, and utility details before submitting plans. California law gives cities 60 days for ministerial review of a complete, compliant ADU application. Plan extra time before submittal for survey work, drawings, utility checks, and any corrections your designer or builder needs to resolve.

Financing

Most Hollywood homeowners compare renovation loans, construction loans, HELOCs, and cash-out refinancing. ADU-focused lenders can underwrite against after-build value when the new unit materially increases rent or resale potential. Compare monthly payment, draw schedule, appraisal approach, and whether rental income from the future ADU can support underwriting.
